long loading times

[Fornax]

Hi everybody,

I have the same problem as the guy in this thread (where nobody answered yet): http://forum.1cpublishing.eu/showthread.php?t=14125

The games themselves (KB The Legend German DVD version and AP Demo) run perfectly but everytime I enter a combat, change the location or load a saved game, shortly: everytime the loading screen appears the computer hangs for several minutes.
The G15 display shows CPU load of about 5% and the HDD LED flashes every 5-10 seconds, so I think the computer has hardly anything to do.

My system:
Core i7 920
12 GB RAM
Radeon 5850
Win7 64bit

Can anybody help?
